I build tools that make working in the terminal faster and less painful. Most of my work lives in the gap between “there should be a tool for this” and “I guess I have to write it myself.”

By day I do security engineering. Outside of that: CTFs, open source tooling, and occasionally fixing things I depend on upstream.

This site is a working portfolio — every project card either runs live in the browser, plays back a terminal recording, or lets you play the thing directly. No screenshots of code.
